Building the web
with purpose
I'm a seasoned Senior Software Engineer with a decade of experience turning complex requirements into pixel perfect, performant front-end solutions. My work spans high-traffic government platforms, global religious organizations, and enterprise SaaS. Always with an eye on what users actually experience.
I believe great engineering is about more than working code. It's about accessible interfaces, maintainable architecture, and teams that are set up to succeed. I've mentored engineers, driven technical direction, and translated design vision into production-ready systems.
The full stack
Where I've made an impact
Provided operational support and built components for one of the highest-traffic government websites in the U.S. Focused relentlessly on performance, accessibility, and scalability across a wide range of devices and platforms. Led the adaptation of web components to align with the latest United States Web Design System (USWDS), achieving WCAG AAA compliance. Collaborated with design and product teams to create responsive, accessible components.
Managed large-scale projects and pioneered serverless architecture using AWS Lambda to optimize performance for high-traffic international sites. Spearheaded the migration of legacy Handlebars codebases to React, dramatically improving maintainability and developer velocity. Implemented Progressive Web Application patterns, improving load times and offline reliability.
Worked closely with clients including Western Governors University and Graduation Alliance to build user-centric web solutions. Collaborated with design teams to establish scalable web design systems, ensuring consistency across platforms. Engaged directly with clients to align technical deliverables with business goals and user experience standards.
Areas of deep expertise
